SPECIFICATION forming part of Letters Patent No. 226,787, dated April20, 1880.

' Application filed March 10, 1880. (No model.)

To all whom it may concern:

Be it known that I, GEORGE E. PURPLE, of Howard City, in the county ofMontcalm and State of Michigan, have invented a new and valuableImprovement in Sand-Boxes; and I do hereby declare that the following isa full, clear, and exact description of the construction and operationof the same, reference being had to the annexed drawings, making a partof this specification, and to the letters and figures of referencemarked thereon.

Figure 1 of the drawings is a representation of a longitudinal sectionof my improved sandbox applied to a hub. Fig. 2 is a front view of thehood, showing its interior construction; and Fig. 3 is a like view ofthe hub end.

This invention has relation to improvements in sand-boxes forvehicle-wheels; and it consists in certain novel arrangement andconstruction of the parts of the box, as will be hereinafter more fullyset forth.

In the annexed drawings, the letter A des ignates the axle-arm, having ashoulder, a, at its union with the squared body I) of the axle and Bisthe wheel-hub, constructed in the usual way and passed on and secured tothe arm in any suitable way.

The hub is provided with a band, a, at its inner end, having a bearing,0, and a flange, c, at right angles to the length of the hub, thebearing resting against the end thereof and the flange projecting outbeyond the perimeter of the hub, as shown in Fig. 1.

Exterior to the bearing and concentric with the band 0 is a projectingannular flange, d, that forms a chamber, 0, around the squared part b ofthe axle.

The band 0, with its bearing 0 and flanges c d, may, if desired, be madein one piece of malleable east-iron, brass, or other metal.

D indicates a metallic hood on the axle and covering rather more thanhalf of the inner end of the hub, and of sufficient interior width toreceive the flange c of band 0. This hood projects over the hub somewhatbeyond the hub-band c, and is open below, and is attached to the axle bymeans of a clip, cl. It is provided with an inwardly-projecting U-shapedsleeve, e, fitting s'nugly on the axle at that part adjoining theshouldera and terminating thereat, which sleeve is provided at its freeend with a flange, f, of a size to be received in chamber 0, and workingagainst the bearing c.- The curvature of this flange is concentric withthat of the hood.

The hood, with its sleeve, flange, and clip, may be cast, if desired, inone piece, and serves to prevent the direct access of mud or sand or ofother foreign matter to the axle-arm.

The flange'c prevents semtliquid mud running down under the hub, andcauses it to drop from the open bottom of the hood.

The function of the flange c is important in that it prevents mud fromaccumulating under the hood or getting in any quantity uir der it, andin that it forms, with the hood, the flange f, and the sleeve 0, alabyrinth which effectually excludes dry dust. Should dust accidentallybe blown into the passage thus formed, the flan gef shuts it 011' fromthe bearing 0 and axle-box, and at the next revolution of the wheeldischarges it out of the hood through its open bottom.

What I claim as new, and desire to secure by Letters Patent, is-

In a sand-guard for vehicle-wheels, the hubbaud 0, having the flange cat right angles to the length of the hub, and the annular flange d,concentric with band 0, in combination with the hood D, covering theupper part of the hub and open at bottom, the sleeve 0, fitting on theaxle projecting from the hood andprovided with the flange f, workingagainst the bearing 0, substantially as specified.

In testimony thatl claim the above I have hereunto subscribed my name inthe presence of two witnesses.

GEORGE E. PURPLE.
